and biologically active tissue engineering scaffolds, all of which are still in their infancies. With
such a broad range of uses, there has been the parallel demand for new fabrication processes or the
application of existing techniques to some of the new biomaterials.
Although many of the biomaterials used in the gastrointestinal tract have good safety profi les,
issues have been raised about the long-term safety and effi cacy of some of the newer materials, par-
ticularly relating to degradation products or migration of the implanted material. Further develop-
ment of the materials will resolve many of the issues raised and improve their effi cacies.
